What is aging?

Aging is actually one of nature’s least understood processes. It is a genetically determined and environmentally modulated process of growing old.

It is an accumulation of detrimental changes at the molecular and cellular levels and ultimately at the levels of tissues and organs resulting in disease and increased risk of mortality and morbidity (Singh and Newman 2011)

Defined as an age-related decrease in viability and increase in vulnerability, aging decreases our capacity to respond to external stresses and ability to function making us more vulnerable to diseases.
